<p>[QUOTE=&quot;-jeffB, post: 3988588, member: 27832&quot;]Okay, I&#039;m confused now -- I didn&#039;t think anything in the thread was saying blue light was a <i>bad</i> thing.</p><p><br /></p><p>Halogen bulbs run hotter than conventional incandescents, so they produce more blue light. That&#039;s good for capturing color (i.e. toning). If you shoot with a conventional incandescent (or another &quot;warm white&quot; bulb), you can fiddle with color balance (using filters or whatever) to make it look right, but blue detail will suffer. Under the covers, your photo app is <i>amplifying</i> all the blue levels from the original photo to increase their intensity, and that also amplifies the <i>noise</i> in that channel.</p><p><br /></p><p>As an aside, I wish we didn&#039;t use &quot;cool white&quot; to refer to <i>higher</i> color temperature and &quot;warm white&quot; to refer to <i>lower</i> color temperature. I guess we made that choice when &quot;cool white&quot; was diffuse light from the (cold) sky, and &quot;warm white&quot; was light from, well, fire. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie11" alt=":rolleyes:" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
